PROBLEM TO BE SOLVED: To avoid falling into an uncontrollable state of at least an intake control valve, when driving voltage is reduced, in driving control of the intake control valve for performing inertial supercharging. SOLUTION: An engine system 10 has an engine 200 having an impulse valve 224 common to the whole cylinders equipped in the engine 200 in a communicating tube 206 arranged downstream of a surge tank 223, and executes driving control of an impulse valve in an impulse charge area. In valve opening control in this control, an ECU 100 corrects a valve opening side switching angleζ1 for expressing a rotation angle of a rotor for transferring a driving current Iq to PID control, to the reduction side in response to a reduction degree of driving voltage Vdc, and similarly in valve closing control, corrects a valve closing side control switching angleζ2 for expressing the rotation angle of the rotor for transferring the driving current Iq to the PID control, to the increase side in response to the reduction degree of the driving voltage Vdc.
